FLIRTDB - A community driven collection of IDA FLIRT signature files

  •        102

Fast Library Identification and Recognition Technology, also known as FLIRT, is IDA's internal symbols identifier that searches through disassembled binaries in order to locate, rename, and highlight known library subroutines. FLIRT elimates the need to analyze functions that could be understood simply by reading documentation or source code from the library it came from and reduces the amount of work required in order to reverse and understand symbol-stripped binaries by a considerable amount. The input to the system is a library file (.lib on Windows) from a library of choice while the output is a signature file (.sig) stored under /sig (and only there or else IDA won't find it). Using one of the tools (plb/pcf/pelf) (provided here for paying customers) you convert all the functions in the library to signatures stored in a PAT file (.pat). The final stage in creating a signature file involves converting the generated PAT file into a .sig file usable by IDA with the use of sigmake. The problem with this is that sometimes collisions will exist for signatures since the method Hex-Rays uses is not fool proof. When an error occurs an EXC (.exc) file is created. In order to ignore collisions, simply edit this file by removing the first few comments (lines that start with ';') and re-run sigmake.

gef - GEF - GDB Enhanced Features for exploit devs & reversers

  •    Python

GEF is a kick-ass set of commands for X86, ARM, MIPS, PowerPC and SPARC to make GDB cool again for exploit dev. It is aimed to be used mostly by exploiters and reverse-engineers, to provide additional features to GDB using the Python API to assist during the process of dynamic analysis and exploit development. It has full support for both Python2 and Python3 indifferently (as more and more distros start pushing gdb compiled with Python3 support).

sk3wldbg - Debugger plugin for IDA Pro backed by the Unicorn Engine

  •    C++

This is the Sk3wlDbg plugin for IDA Pro. It's purpose is to provide a front end for using the Unicorn Engine to emulate machine code that you are viewing with IDA. The plugin is dependent on the Unicorn engine. Because IDA is 32-bit, you MUST have a 32-bit build of the Unicorn library for your IDA platform (Windows, Linux, OS X).

python-idb - Pure Python parser and analyzer for IDA Pro database files (.idb).

  •    Python

python-idb is a library for accessing the contents of IDA Pro databases (.idb files). It provides read-only access to internal structures such as the B-tree (ID0 section), name address index (NAM section), and flags index (ID2 section). The library also provides analysis of B-tree entries to expose logical structures like functions, cross references, bytes, and disassembly (via Capstone). An example use for python-idb might be to run IDA scripts in a pure-Python environment. Willem Hengeveld (mailto:itsme@xs4all.nl) provided the initial research into the low-level structures in his projects pyidbutil and idbutil. Willem deserves substantial credit for reversing the .idb file format and publishing his results online. This project heavily borrows from his knowledge, though there is little code overlap.

pyrebox - Python scriptable Reverse Engineering Sandbox, a Virtual Machine instrumentation and inspection framework based on QEMU

  •    C

PyREBox is a Python scriptable Reverse Engineering sandbox. It is based on QEMU, and its goal is to aid reverse engineering by providing dynamic analysis and debugging capabilities from a different perspective. PyREBox allows to inspect a running QEMU VM, modify its memory or registers, and to instrument its execution, by creating simple scripts in python to automate any kind of analysis. QEMU (when working as a whole-system-emulator) emulates a complete system (CPU, memory, devices...). By using VMI techniques, it does not require to perform any modification into the guest operating system, as it transparently retrieves information from its memory at run-time. Several academic projects such as DECAF, PANDA, S2E, or AVATAR, have previously leveraged QEMU based instrumentation to overcome reverse engineering tasks. These projects allow to write plugins in C/C++, and implement several advanced features such as dynamic taint analysis, symbolic execution, or even record and replay of execution traces. With PyREBox, we aim to apply this technology focusing on keeping the design simple, and on the usability of the system for threat analysts.

barf-project - BARF : A multiplatform open source Binary Analysis and Reverse engineering Framework

  •    Python

The analysis of binary code is a crucial activity in many areas of the computer sciences and software engineering disciplines ranging from software security and program analysis to reverse engineering. Manual binary analysis is a difficult and time-consuming task and there are software tools that seek to automate or assist human analysts. However, most of these tools have several technical and commercial restrictions that limit access and use by a large portion of the academic and practitioner communities. BARF is an open source binary analysis framework that aims to support a wide range of binary code analysis tasks that are common in the information security discipline. It is a scriptable platform that supports instruction lifting from multiple architectures, binary translation to an intermediate representation, an extensible framework for code analysis plugins and interoperation with external tools such as debuggers, SMT solvers and instrumentation tools. The framework is designed primarily for human-assisted analysis but it can be fully automated. All packages were tested on Ubuntu 16.04 (x86_64).

obfusion - Obfusion - C++ X86 Code Obfuscation Library

  •    C++

This library handles obfuscation of assembled X86 machine code in order to make it harder to read and analyze during the reverse engineering process. Should work very well with obfuscating shellcode that is later embedded with executable files. If shellcode is known to security products, the obfuscation process should make it bypass any signature detection scans.
